Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A management method for managing access by a plurality of transfer devices to a content stored on a content server, the transfer devices being connected to a playback device and being associated with respective identifiers, the method being characterized in that it comprises a prior stage including a requesting device, distinct from said at least one transfer device, requesting through a network authorization to access the content to a server delivering access data, the authorization request being accompanied by a subset of target transfer device identifiers selected, on a requesting device, from a list of target transfer device identifiers that will be authorized to access the content, followed by a step of receiving from the network, by said requesting device, access data, for accessing the content, and a step of storing said access data in said requesting device, the access data including said target transfer device identifiers, and a stage of accessing the content, including: transmitting the stored access data including said subset of target transfer device identifiers from a requesting device to said plurality of transfer devices; receiving, by said plurality of transfer devices, access data including said subset of target transfer device identifiers from said requesting device distinct from said transfer devices; and in a transfer device wishing to access the content, comprising transmitting an access request to the content, the request including the access data received from the requesting device distinct from said transfer device and an originating transfer device identifier that identifies the transfer device originating the access request; and the transfer devices receiving and transmitting the content to the playback device if the originating transfer device identifier of the at least one transfer device, included in the access data originating the transmission corresponds to an identifier value authorized to access the content.
This invention relates to content access management in a networked system and addresses the problem of controlling which transfer devices can access content stored on a server. The method involves a requesting device, separate from the transfer devices, initiating an authorization process. The requesting device sends a request to a server for authorization to access specific content. This request includes a subset of identifiers for target transfer devices that are intended to be authorized. In response, the requesting device receives access data from the server, which contains the authorized target transfer device identifiers. This access data is then stored on the requesting device. Subsequently, the access data, including the subset of target transfer device identifiers, is transmitted from the requesting device to multiple transfer devices. Each transfer device receives this access data. When a transfer device wishes to access the content, it sends an access request to the content server. This request includes the received access data and its own unique originating transfer device identifier. The content server verifies if the originating transfer device identifier within the received access data is authorized to access the content. If authorized, the content is transmitted to the transfer device, which then forwards it to a connected playback device.
2. A management method according to claim 1 , characterized in that the list of target transfer device identifiers relates to a single group of users.
This invention relates to a management method for transferring data between devices in a networked system, particularly in environments where multiple users share or access common resources. The problem addressed is the need to efficiently and securely manage data transfers among devices associated with a specific group of users, ensuring that transfers are restricted to authorized devices within that group. The method involves maintaining a list of target device identifiers, where each identifier corresponds to a device eligible to receive transferred data. The list is dynamically updated based on user group membership, ensuring that only devices associated with the designated group can participate in transfers. This prevents unauthorized devices from accessing or receiving data intended for the group. The method further includes verifying the identity of each target device before initiating a transfer, using authentication mechanisms such as digital certificates or network credentials. Once verified, data is securely transmitted to the authorized devices, with optional encryption to protect the data during transit. The system may also log transfer activities for auditing and compliance purposes. This approach improves security and efficiency in multi-user environments by restricting data transfers to a predefined group, reducing the risk of unauthorized access or data leaks. It is particularly useful in enterprise networks, collaborative platforms, or cloud-based systems where controlled data sharing is essential.
3. A method according to claim 1 , characterized in that the receiving access data from said requesting device is preceded by the requesting device transmitting access data to the at least one transfer device, and in that the requesting device informs the content server that said transmission step has been performed.
This invention relates to secure data transfer systems, specifically methods for managing access data between a requesting device, a transfer device, and a content server. The problem addressed is ensuring secure and authenticated data exchange while preventing unauthorized access to content. The method involves a requesting device initiating a data transfer by first transmitting access data to at least one transfer device. The transfer device then receives this access data and forwards it to a content server. Before the content server processes the access data, the requesting device must notify the content server that the transmission to the transfer device has been completed. This notification step ensures that the content server only accepts access data that has been properly relayed through the transfer device, enhancing security. The transfer device acts as an intermediary, receiving and forwarding access data while potentially performing additional security checks or transformations. The content server, upon receiving confirmation from the requesting device, verifies the transmission and grants or denies access based on the received access data. This multi-step process prevents direct unauthorized access to the content server while maintaining a secure communication channel. The method is particularly useful in systems where content distribution must be controlled through intermediaries, such as in digital rights management (DRM) or secure cloud storage.
4. A system comprising a requesting device including a requesting module for requesting, through a network to a server delivering access data, authorization to access a content stored on a content server, the content being for accessing by a plurality of transfer devices, said plurality of transfer devices being connected to a playback device and being associated with respective transfer device identifiers, the requesting device being characterized in that the request is accompanied by the transfer device identifiers of a subset of target transfer device identifiers authorized to access the content, and in that it further comprises: a processor; and a non-transitory computer-readable memory storing the requesting module, a receiving module and a transmitting module, wherein when executed by the processor: the receiving module receives, from the network, access data for accessing the content, the access data including said target transfer device identifiers authorized to access the content; the storing module store the access data; and the transmitting module transmits the access data including said subset of target transfer device identifiers to the plurality of transfer devices; a transfer device comprising in order to access the content: a receiving module receives access data including said subset of target transfer device identifiers previously obtained by a requesting device, the access data including a first target transfer identifiers that identify transfer devices authorized to access the content; a requesting module requests access to the content, the access request including the access data including said subset of target transfer device identifiers and a second identifier that identifies of the transfer device originating the access request; and an enabling module receives the content if the second identifier of the at least one transfer device originating the request corresponds to an identifier value authorized to access the content.
This invention relates to a system for managing access to digital content across multiple transfer devices connected to a playback device. The problem addressed is controlling content access in environments where multiple devices may share a single playback system, ensuring only authorized devices can access specific content. The system includes a requesting device that communicates with a server to obtain access data for content stored on a content server. The requesting device sends a request to the server, including identifiers for a subset of transfer devices authorized to access the content. The server responds with access data containing these authorized identifiers. The requesting device then stores and transmits this access data to the connected transfer devices. Each transfer device receives the access data, which includes the authorized identifiers. When a transfer device requests access to the content, it sends the access data along with its own identifier. The system verifies whether the transfer device's identifier matches one of the authorized identifiers in the access data. If verified, the transfer device is granted access to the content. This ensures only pre-authorized devices can access the content, enhancing security and access control in multi-device playback environments.
